This repository contains the data processing, predictive modeling workflows, and the implementation of a residential housing price estimation tool.
- Workflow: Combines numerical and categorical engineered datasets into a unified master file.
- Key Files:
numerical_engineered_data.csv,categorical_engineered_data.csv - Output:
final_model_ready_data.csv
- Tool: A custom-built estimation tool featuring a
predict_house_pricefunction. - Functionality: Takes user-defined property features (e.g., quality, square footage, year built) as input.
-
Notebook: Focuses on establishing a baseline using a
RandomForestRegressor. -
Performance: Achieved an
$R^2$ of approximately 0.89.
- Notebook: Focuses on linear modeling techniques.
-
Preprocessing: Implementation of a
PipelineincludingSimpleImputerandStandardScaler. -
Optimization: Applied
GridSearchCVforalphatuning. -
Performance: The tuned Ridge model with log-transformed targets achieved an
$R^2$ of ~0.91.
The findings and the predictive logic are being visualized in a Tableau dashboard to communicate regional insights and model performance to stakeholders.
